ZX-Frankenstein 2.0 - Kempston Adapter, AY and SD.
A mish-mash of designs to bring you a device with a Kempston joystick port, an AY Sound Chip mixed with Maxduino, the firmware everyone loves for loading games from an SD into your ZX Spectrum
New in 2.0 is the addition of AY Sound capabilities is awesome for adding real sound to models of spectrums that never had an AY chip.
